Abstract
The invention relates to the field of failure analysis, in particular to a dye test. The invention provides a tool for the extraction of a BGA (Ball Grid Array) in the dye test. The tool adopts an I-shaped structure and comprises a cross rod and handles fixed at the end parts of the cross rod. The invention further provides a use method of the tool for the extraction of the BGA in the dye test. The use method comprises the following steps: A, roughing the surface of the dyed BGA by using a lettering pen; B, smearing a layer of super glue on the surface of the BGA; C, pressing the middle part of the cross rod of the tool onto the super glue on the surface of the BGA; and D, after the super glue is solidified, fixing a PCB (Printed Circuit Board), and clenching and upwardly extracting the handles at the two ends of the cross rod to extract the BGA. The tool has the advantages of simple structure, convenience in assembly, low cost, good rigidity and convenience in use; and the method is simple, convenient and quick to operate, no damage to a welding point of the BGA exists, and the efficiency of the dye test and the accuracy of test result judgment are greatly improved.
Description
Technical field
The present invention relates to the failure analysis field, particularly a kind of dye test method.
Background technology
Dye test has another name called the red ink test, is called " dyeing and perk " on the specialty.Its method is to utilize the red ink of suitable viscosity to be expelled to suspect have under the BGA of failure welding, red ink to be confirmed enters under the BGA fully, after treating that Deng a period of time or baking red ink has been done, BGA is levered up from pcb board with instrument, by observe BGA solder joint and PCB pad the dyeing situation, determine the welding effect of BGA.The instruments such as BGA levers up that normally used instrument is that a word rises, tweezers and vice lever up BGA by actions such as sticking up, dig, pull out, and lever up in the process without fixing working specification, fully by virtue of experience operate.The method that use that a word rises, the work such as tweezers and vice levers up BGA is easy to damage the solder joint of BGA periphery, and speed is slow, and the length that expends time in has a strong impact on judgement and the operating efficiency of experimental result.
Therefore, BGA in the dye test is levered up how fast, efficient, safely, judge in order to carry out rapidly and accurately the result, become failure analysis field problem demanding prompt solution.
Summary of the invention
Dye test BGA pulls out the problem that speed is slow, efficient is low and easily damage solder joint in the prior art in order to solve, and the invention provides following technical scheme:
A kind of frock of pulling out for dye test BGA, this frock is I-shaped structure, comprises cross bar and is fixed in the handle of described crossbar end.
As a preferred embodiment of the present invention, described cross bar has rectangular structure.
As another kind of preferred version of the present invention, the material of described cross bar and described handle is iron and steel.
A kind of using method of the frock of pulling out for dye test BGA, the method may further comprise the steps:
A, use Lettering pen will be beaten rough through hyperchromatic BGA surface;
B, smear one deck seccotine on the BGA surface;
Be pressed on the seccotine on BGA surface in the middle part of C, the cross bar with described frock;
D, after seccotine solidifies, fix pcb board, the handle at the described cross bar two ends of holding with a firm grip upwards pulls up, and BGA is pulled out.
As a preferred embodiment of the present invention, the seccotine among the described step B is quick steel.
The present invention has the following advantages: tool structure of the present invention is simple, and is easy to assembly, and cost is low, and good rigidly is easy to use; The inventive method is easy and simple to handle, and is quick, harmless to the BGA solder joint, greatly improved efficient and the result of the test Accuracy of Judgement of dye test.

The specific embodiment
The below elaborates this process implementing example, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
Shown in Fig. 1 tool structure schematic diagram of the present invention, a kind of frock of pulling out for dye test BGA, this frock is I-shaped structure, comprises cross bar 1 and is fixed in the handle 2 of cross bar 1 end.Cross bar 1 is rectangular structure.Cross bar 1 can also be semicylinder structure or triangulo column structure or other similar structures, as long as length direction has one side for the plane, can carry out bonding getting final product with the BGA surface easily.The material of cross bar 1 and handle 2 is iron and steel, just can bear enough pulling force like this when BGA pulls out.
Shown in Fig. 2 frock occupation mode of the present invention A schematic diagram and Fig. 3 frock occupation mode of the present invention B schematic diagram, a kind of using method of the frock of pulling out for dye test BGA, the method may further comprise the steps:
A, use Lettering pen will be beaten rough through hyperchromatic BGA surface;
B, smear one deck seccotine on the BGA surface, the seccotine that uses in the present embodiment is quick steel;
C, cross bar 1 middle part of frock is pressed on the seccotine on BGA surface, the modes of emplacement of frock can be placed according to the mode such as Fig. 2, also can place according to the mode such as Fig. 3;
D, after the quick steel of seccotine solidifies, fix pcb board, the handle 2 at cross bar 1 two ends of holding with a firm grip upwards pulls up, and BGA is pulled out.
The above; it only is the part of the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
